Im stripping and rebuilding my gearbox today with straight cut gears.

Does anyone have, or know where i can get an exploded image or diagram of the internals just incase i get stuck?

Never done a gearbox before!!

 

Haynes I believe has one?
But if you pay attention as you strip it down it's really not very hard, you will need a 5th gear puller though (or lots of heat, leverage and patience).

 

they're a pain in the arse IMO, fifth gear puller and getting them back together is awkward.
essentially simple, just getting selector forks and shafts to drop back in properly is frustrating, or at least i found them to be.

 

Not just you mate, they are fiddly getting back together and I've done loads!
